How to Use the Authorize.net MCP in Windsurf

Q: What's the difference between voiding and refunding for Windsurf and Authorize.net?

A void (voidtransaction) cancels a payment that hasn't settled yet. A refund (refundtransaction) returns money from a payment that has already settled. Windsurf's Cascade agent can handle both situations.

Let Windsurf's Cascade agent handle your Authorize.net payments, refunds, and customer profiles in one shot. No hand-holding required.

Full-Cycle Customer and Payment Management

Stop clicking through menus. Tell Cascade to sign up a new customer and charge their first month. It’ll chain `create_customer_profile`, `add_payment_profile`, and `auth_capture_transaction` on its own. You just give the high-level goal. Cascade figures out the steps, runs them against your Authorize.net account, and shows you the result. It’s the fastest way to get from A to B.

Manage Holds and Captures with Windsurf

This server gives Windsurf the tools to manage the whole transaction lifecycle. You can prompt it to place a temporary hold on a card with `auth_only_transaction` before you ship an order. When you're ready, just tell Cascade to capture the funds. It will find the original hold and run `prior_auth_capture`. If the customer cancels, it can just as easily run `void_transaction` to release the hold. Your agent handles the details.

Automate Reconciliation and Reporting

Reconciliation doesn't have to be a manual chore. Ask Windsurf to 'Find and refund order #12345.' It can use `get_transaction_details` to locate the specific charge and then execute a `refund_transaction` with the correct parameters. Your agent can also pull daily reports for you. A simple prompt to get a list of pending transactions is all it takes for Windsurf to run `get_unsettled_transactions` and give you a clean summary.

Common questions about Authorize.net MCP in Windsurf

Just tell Windsurf what you want to do, like 'Charge Jane Doe $50 for her order.' Cascade will automatically find and use the `auth_capture_transaction` tool.

Yes. Give it an original transaction ID and an amount. Windsurf will use the `refund_transaction` tool to process the refund in your Authorize.net account.

A void (`void_transaction`) cancels a payment that hasn't settled yet. A refund (`refund_transaction`) returns money from a payment that has already settled. Windsurf's Cascade agent can handle both situations.

It's simple. You can install it from the built-in MCP Marketplace with one click. Or, you can add the server URL manually in your Windsurf settings.

This server only processes transaction and customer profile information you explicitly provide. It sends payment card numbers and expiration dates to Authorize.net's API but doesn't store them. Vinkius runs each MCP server in an ephemeral sandbox, so your data is gone after the request.
